Making salts from solutions
we can make soluble salts by reacting an acid and an alkali.
acid + alkali - salt + water
- When a soluble salt is made from an alkali and an acid, an indicator can be used to show when a reaction is complete.
- insoluble salts can be made by reacting two solutions to produce a precipitate.
- precipitation is an important way of removing some metal ions from industrial waste water
